I just installed in my new home. I already knew the effectiveness of the brand with my family. Living in an apartment, it is not easy to adjust the heating temperature when it's cold and wet because of the heat from the other apartments (tidal and tired of doing the yoyo with heating). I decided to buy this one for the room, on top of the cabinet. Farewell my allergies related to dust mites and farewell feeling cold, humidity, and hello small heating savings! I bought a 40m for the main room, where I am most regularly and where the kitchen odors are present. I could also enjoy the redemption offer on the website of the brand.
